Is your copy of V-Station 32bit? If so, I read somewhere recently that multiple instances of the same 32bit VST can sometimes crash bit bridge. Some possible workarounds are:
1) Try using JBridge.
2) Create a COPY of the VST DLL in your VST plugins folder for each instance you want to use, rescan, then make sure to use only a single instance of each.
3) Upgrade V-Station to the 64bit version.
If you are already using 64bit plugins, then I'd suspect a wonky audio driver is causing this (and you shouldn't see any bit bridge instances running).
